UIImageView不動畫

Question

我的應用程序內有以下代碼，但它不會動畫UIImageView，誰能告訴我爲什麼？

UITableViewCell* cell = [selectedTable cellForRowAtIndexPath:selectedPath]; 

    NSArray* myImageArray = [NSArray arrayWithObjects: 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked117x11" ofType:@"png"]], 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked217x11" ofType:@"png"]], 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked317x11" ofType:@"png"]], 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked417x11" ofType:@"png"]], 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked517x11" ofType:@"png"]], 
          [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked617x11" ofType:@"png"]], 
          nil]; 


    cell.imageView.animationImages = myImageArray; 
    cell.imageView.animationDuration = 4.20; 
    cell.imageView.animationRepeatCount = 1; 
    [cell.imageView startAnimating]; 
    [NSTimer scheduledTimerWithTimeInterval:4.0 
            target:self 
            selector:@selector(methodToInvokeAfterAnimationIsDone) 
            userInfo:nil 
            repeats:NO]; 

Answer 1

你應該使用這樣的：

NSArray* myImageArray = [NSArray arrayWithObjects: 
          [UIImage imageNamed:@"boxBeingChecked117x11.png"]], 
          [UIImage imageNamed:@"boxBeingChecked217x11.png"]], 
          [UIImage imageNamed:@"boxBeingChecked317x11.png"]], 
          [UIImage imageNamed:@"boxBeingChecked417x11.png"]], 
          [UIImage imageNamed:@"boxBeingChecked517x11.png"]], 
          [UIImage imageNamed:@"boxBeingChecked617x11.png"]], 
          nil]; 

你需要給名稱的文件，而不是路徑的，在imageNamed：方法。

確保imageView的highlighted屬性設置爲NO，否則上面的代碼將不起作用。如果要爲突出顯示的圖像製作動畫，請使用highlightedAnimationImages。
